Batch file 如何使用FIND语句和嵌套IF条件

我试图在批处理中使用find语句和if条件，但执行没有输入if条件，而是在第一个if语句处停止：

@echo off  
find /i "DA" E:\LogFiles_List.txt > nul  
pause  
if errorlevel 1  
(  
echo DA not found  
pause    
)  
else  
(  
find /i "Error" E:\hello.txt > nul   
 if errorlevel 0 (   
 echo Error found in hello.txt   
pause  
 ) else (   
 echo Error NOT found in thefile.txt   
pause  
 )   
)  

学习if的语法，如if/？中所述？。偏执论必须与if或else在同一条线上。以下是更正后的代码：

@echo off  
find /i "DA" E:\LogFiles_List.txt > nul  
pause  
if errorlevel 1 (  
  echo DA not found  
  pause    
) else (  
  find /i "Error" E:\hello.txt > nul   
  if errorlevel 0 (   
    echo Error found in hello.txt   
    pause  
  ) else (   
    echo Error NOT found in thefile.txt   
    pause  
  )   
)
